Hi all,I'm embarking on making the splash rails for my Monaco and i have a few questions.- PositionI was thinking of putting them inline with where the hull goes vertical on the sides.To add to this i am also in 2 minds as to position them parallel to the paint line on the side, of parallel to the top edge of the hull.- LengthMy boat is looking more like a newer version of a Chris craft racing runabout, so i was going to run them around 1/4 length of the hull. This lines up with where the hull starts to curl under.- Thickness1 inch (25mm) was my guess

I'm open to any advice that anyone wishes to send my way.thankschrisSydney Australia

Hi Chris, good question but first let's make sure we're talking the same thing: on a classic hull the spray rails are pieces mounted along the bottom edge of the sides at the chines, they run from bow to stern and redirect splashing water "spray" from the hull back down to the surface of the water. The other thing, which I think you are talking about, is actually a rub or bumper rail. They are mounted on the sides of the hull typically in the aft third or so of the hull length and protect the hull side from rubbing or banging against a dock or pier. They usually run from the point like you said about where the sides are vertical then aft to the transom. They may be parallel to the waterline but more often they are placed along the widest part of the curve of the sides. That may make it parallel to the upper edge of the side (sheer) or some angle in between the sheer and the waterline. That will depend on the hull shape. Glen L boat plans will show how the rub rail is installed. One inch is about right. Some designs are tapered from 1 inch at the hull down to maybe 3/4 inch or 5/8 inch thick at the outer edge, but you can make it however you like.

Chris, Here are pictures of the splash rails I recently added to my Gentry. I did it in two laminations, each one came out 5/8". So the total width is 1.25". I think one inch would be fine. I haven't had a chance to try them out yet, but planning on doing it this Thursday. I will post something.... Neel
